Dark-State Polaritons for multi-component and stationary light fields
F. E. Zimmer, J. Otterbach, R. G. Unanyan +2
We present a general scheme to determine the loss-free adiabatic eigensolutions (dark-state polaritons) of the interaction of multiple probe laser beams with a coherently driven at…

A Decomposition of Separable Werner States
R. G. Unanyan, H. Kampermann, D. Bruss
We derive an integral convex combination of product states for a range of separable Werner states. Our method consists of expanding the sought-after local density operators in term…

Bi-partite and global entanglement in a many-particle system with collective spin coupling
R. G. Unanyan, C. Ionescu, M. Fleischhauer
Bipartite and global entanglement are analyzed for the ground state of a system of spin 1/2 particles interacting via a collective spin-spin coupling described by the Lipkin-Me…
